Agro-morphological characterization of sorghum collection in Senegal showed a wide range of variation, linked to traits like plant duration, plant height, and yield components. Sorghum accessions or landrace characterized by short duration, high, and low-medium yield components are the most represented in the collection. Simple correlations between variables of different types relating to phenology, vegetative growth, and yield components are very different, showing a relative independence of characters, and thus a wide phenotypic diversity. This diversity can be explained by plant duration, plant height, grain weight per foot, and the shape of the panicle. From these agro-morphological characteristics, varietal groups based on similarity were identified and accessions with interesting agro-morphological characteristics clustered. Racially diversity, dominated by Guinea, caudatum and Durra are also observed. This collection is an interesting breeding material for improving sorghum.
